Claw toe occurs when your toe points down or up and is unable to straighten. It’s often the result of nerve damage from diseases like diabetes or alcoholism, which weakens the muscles in your foot. Without special footwear to accommodate the claw toe, you may develop irritation and calluses.
To treat it:
Change to better-fitting footwear. Avoid high heels and tight shoes.
Do stretches for your toes and toe joints.
Try shoe inserts.
Ask your doctor about surgery.
